As Starfire watches her sister and their friend getting fucked by Isaac's massive cock, she decides to join in on the fun as well. She straddles his waist, taking his huge member in hand and guiding it towards her wet pussy. With a moan, she sinks down onto him, feeling him stretch her tight folds. Blackfire climbs up onto the bed, her legs wrapped around Isaac's head as she positions herself for his tongue to lick her clean.

As Isaac fucks Starfire from behind and eats out Blackfire simultaneously, the girls moan in unison. Starfire gasps as she feels her pussy stretched to its limits by his huge cock, each thrust sending waves of pleasure through her body. Blackfire cries out as Isaac's tongue expertly hits all the right spots inside her, making her squirm beneath him. Raven continues to stroke and suck on Isaac's cock, her other hand reaching down to massage her own clit.
